Title: Improvements in and relating to weighing machines
IPC: G01G19/14
Filed: 1923-12-07
Abstract: 225,705. Denison, G. H., Shoosmith, H., and Denison &. Son, Ltd., S. Dec. 7, 1923. Apparatus fitted to cranes. - A hoisting device is provided with automatic weighing-apparatus of the type in which the hoisting-rope is passed over three or more pulleys adapted to differentiate the load, the weighing- apparatus being combined with a non- autographic integrating-device, for indicating and/or recording the aggregate weight of a series of loads. As shown, the hoisting-rope a passes under two fixed pulleys b, c and over a third pulley d, the load on which is communicated through a series of reduction levers to a lever k connected to an automatic counterbalancing mechanism such as a mercury dash-pot l. An integrating- device such as that described in Specification 3351/09 operates on the end of the lever k and actuates a totalizer X. The motive power for the integrator is derived from a continuously-driven electric motor z adapted to be coupled to the integrator by a one-revolution clutch x controlled by a solenoid q. In order that the weighing mechanism may weigh only when the load reaches a certain height, a switch n in circuit with the solenoid q is suspended from the jib of the crane, so that the members of the clutch x engage only after the switch n has been closed by a rising load. In a modification in which the load is balanced by an automatically traversed counterweight on the lever k, the integrating-device employed is of the type described in Specification 13544/06, and the switch n is inserted in the circuit of the operating motor, which may, when the switch is closed, be started in the usual manner. In a further modification, the switch n is inserted in the circuit of a second motor which through a cam shaft controls the clutch x and operates relieving-mechanism.

Patent GB-1036358-A (GB)
Title: Data transmitting system
IPC: H04L1/14
Filed: 1964-08-04
Abstract: 1,036,358. Telegraphy. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE. Aug. 4, 1964 [Aug. 28, 1963], No. 31064/64. Heading H4P. The invention describes a system which is generally as described in Specification 1,002,705 but which is less susceptible to errors in operation than the earlier arrangement. The system is one in which transmission can take place from a telegraph unit or a data unit, errors being detected by returning received signals to the transmitter for comparison with those transmitted and being corrected by repetition. The transmitter and receiver stores comprise multiple stages, the number of stages to be used being automatically determined by the total transmission time during the changeover from telegraph to data transmission. In Specification 1,002,705 changeover is initiated by transmission of combinations SSSS followed by a long Stop pulse for determination of the transmission time. In the present invention a further sequence SSSS is transmitted at the end of the long Stop. Should a noise pulse have occurred during the long Stop the noise would simulate a Start pulse and, on the return channel, the long Stop signal will not be followed by SSSS. Failure to receive this last signal prevents the transmitter from changing to data transmission and operates an alarm. Detection of an error during data transmission causes an extended Stop pulse to be transmitted in Specification 1,002,705. In the present invention the extension of the normal Stop pulse is one element long, e.g. 20 m.sec., and the transmitter checks the return channel for the presence of this extension at the correct time. If the returned extension is not found the transmitter returns to the telegraph position and an alarm operates. Should a transmitted Start pulse be returned as a Stop pulse a similar action takes place. To prevent accidental disconnection due to the predominance of negative polarity in a succession of characters No. 32, it is arranged that only two consecutive such characters can be sent. If a third appears it is deliberately mutiliated prior to transmission but is stored unmutilated at the transmitter for retransmission which results from detection of the mutilated character.
